From publisher blurb:
Get ready to find the Center of the Earth! With over 30 possible endings!
Your uncle gives you a mysterious book. You read it on your plane ride to Iceland where you are heading for vacation. The book is filled with strange symbols that have been decoded, revealing a secret message. It tells you to descend into the crater of an extinct volcano and to follow the path marked by the three notches. If you do this, you can reach the Center of the Earth. But ahead of you are all sorts of dangers. Earthquakes, floods, total darkness, dinosaurs, and even a strange cult from the Lost City of Atlantis await you. Can you avoid the perils and make it to the Center of the Earth? Open the book and find out. But remember, you can’t turn back.
